Turner said she and Williams always have sleepovers when they’re in the same town.

While at New York Comic Con on Saturday, Turner revealed what they’d do during the evenings: get high and sit in the bathtub.

“Game of Thrones” stars Sophie Turner and Maisie Williams play sisters on the HBO show and are best friends in real life.

During New York Comic Con on Saturday, Turner, 22, explained that she and Williams, 21, have sleepovers whenever they’re in the same place and revealed what they’d do during the evenings, which included getting high and sitting in a bath.

“We’re kind of like loners on Game of Thrones,’ just because the past few seasons Maisie and I have sleepovers every night when we’re shooting or every night whenever both of us are in town,” she said. “We just used to sit there and eat and watch stupid videos and smoke weed.”

She added: “I don’t know if my publicist will kill me for saying this. We’d get high and then we’d sit in the bath together and we’d rub makeup brushes on our faces. It’s fun.”
